Title: Mechanism testing adhesion properties of polythene films - uses test stripping technique under controlled conditions
Inventor: WARTENBERG ERWIN W DR
IPC: G01N19/04
Filed: 1975-03-29
Abstract: The mechanism tests the quality of adhesion of a polythene film or layer, or similar adhesive layer, on an undulying surface, typically for use in the food packing industry, in which a sample of the film is stripped off under carefully controlled conditions. The mechanism allows the adhesive tape to be removed in a controlled and monitored way. This is achieved by attaching the adhesive test tape to the sample in a groove in the mechanism, and pulling it off by means of a carriage which travels up a guide at 45 degrees to the surface of the sample. In this way the tape is pulled off vertically from the sample surface. The force is supplied by an elastic band and is monitored by a spring instrument which records the maximum force applied during the test.

Title: Thin-walled pipe bending device - produces eccentric corrugations to bend pipe without internal stresses
Inventor: GALPERIN ABRAM ISAEWITSCH
IPC: B21D9/14
Filed: 1975-05-13
Abstract: Thin-walled pipe bending device includes an expander block formed by a supporting shoe and a punch mounted on the shoe. The expander block is introduced into the pipe to make a corrugation on the pipe, eccentric to the pipe axis, thus bending the pipe. The punch is in the form of a ring which is interrupted in the region of the shoe and is composed of individual elements around the perimeter. A number of jacks have their axes arranged radially with respect to the ring and their movable members articulated to the respective elements of the punch. The jacks are connected to the shoe. For bending large diameter thin-walled pipes for use as curved sections of trunk pipelines carrying gases, petroleum products, or water. An eccentric corrugation is formed such that the height of the corrugation on one of the pipe generatrices under the supporting shoe is zero and is a maximum on the diametrically opposite generatrix. This increases the efficiency of bending, thus requiring fewer corrugations for a given angle of bending. Internal stresses in the pipe walls are reduced so that the pipe life is extended. The device can be accurately positioned in the tube.

Patent DE-2619430-A1 (DE)
Inventor: ROHNER JOACHIM
IPC: B65H63/08
Filed: 1976-05-03
Abstract: In order to prevent a thread break from remaining unnoticed on a winding apparatus, because the broken thread catches again on the run-on bobbin, with the result that the thread signal monitored by a thread regulator is absent only for an extremely short time, the thread monitor (9) is used to control a self-locking quick-action thread clamp (8). The quick-action thread clamp then, immediately after the thread break, retains the thread (5) coming from the run-off bobbin (6), so that it can no longer advance towards the run-on bobbin (3). The thread signal can thereafter with certainty no longer occur and the thread break can no longer remain undiscovered. <IMAGE>
